CO1 > F18 - 1: the standardized signal output (terminals
11/12) is not available anymore as a control output. The maxi-
mum flow set point (with boost, if applicable) is demanded as
a 0 to 10 V signal at the standardized signal output.
Function block parameters:
Lower transmission range: 0.0 to 150.0 °C (0.0 °C)
Upper transmission range: 0.0 to 150.0 °C (120.0 °C)
